摘要
采用磁控溅射技术在Ti6Al4V合金表面制备了含Ag和不含Ag的Ta2O5/Ta2O5/Ta2O5-TiO2/TiO2/Ti多层复合涂层(分别用Ag-MTa2O5和MTa2O5表示),通过SEM、XRD、EDS、纳米压痕仪、电化学工作站和平板计数法,对涂层试样进行表征与检测。研究结果表明,Ag的掺杂对MTa2O5多层涂层的结构和性能有重要影响。与MTa2O5涂层相比,Ag-MTa2O5涂层表面的晶粒变粗、致密度降低、机械性能和耐腐蚀性能略有下降;但Ag-MTa2O5涂层的抗菌率为100%,显示出优异的抗菌性能。
Ta2O5/Ta2O5/Ta2O5-TiO2/TiO2/Ti multilayer composite coating doped or undoped with Ag was developed on the surface of Ti6Al4V alloy by magnetron sputtering(denoted as Ag-MTa2O5 and MTa2O5).The coating samples were characterized and detected by SEM,XRD,EDS,nano-indentation instrument,electrochemical workstation and plate counting method.The results showed that the doping of Ag played an important role in the structure and properties of the MTa2O5 multilayer coating.Compared with the MTa2O5 coating,Ag-MTa2O5 coating exhibited larger grain,lower density,slightly lower mechanical properties and corrosion resistance,while showing excellent antibacterial property with an antibacterial rate of 100%.
